Generate image with SeeDream 5.0 Pro
ByteDance SeeDream 5.0 Pro — precise image editing with full layer control. Text-to-image, instruction-based editing, and multi-reference composition from up to 9 reference images with 1K/2K output. Billing: 55 credits per image at 1K, 110 at 2K; input images bill 5 credits each after the first (first is free). No grouped/sequential generation.
Asynchronous. Returns a job id (the image is not in this response). Poll GET /v1/images/{id} until status is succeeded — the generated image URLs are in that response’s images array (each { url, position }).
